ntrnovsn BBD-BOTTOM SPRING.

TO ALL WHOM I'l MAY CONCERN:

Be it known thatl l, HEBER G. SEEKINS, of Elyria, in the county ofLorain, and State of Ohio, have invented a new and` improved CompoundBed-Spring for Bed Bottoms; and I do hereby declare that the followingis a full and exact description thereof, reference being had to theaccompanying dra-wing and the letters of reference marliedthereon.

The nature of my invention consists in soconstructing a compoundbed-spring for bed bottoms thatwhcn it is compressed in the ini-ldlc, ashereinafter described, the ends of the upper leaves B B, and of theunder leaves C C', will recede from a central horizontal line, andthereby adapt it to the natural position ofthe body of the occupant-VThe spring is so constructed that all of its parts act in suchcombination that by compression in the middle, as described, the extremeends ofthe lower leaves C C will bear on the supports attached to thebedstead, at its head and foot, before the centres of the spring, wherethe pressure is applied, come in contact with each other-,therebyproducing a double-spring effect or acting-as a double spring on theupper and under sides of sthesanie, and well adapting the spring tosecure'tlie result for which it is designed.

To enable others skilled in the art to multe and use my invention, Iwill proceed to describe its construct-ion aad operation; and firstas toits construction. v

I talco a piece of timber nii-suitable length for a bed, some two inchesin width, and of proper thicknesss, and whenon its edge saw it throughits cent-re the whole length, except about six inches at each end of thesame.v Then commence at each end, on4 both sides, or a distancetherefrom in proportion `to the thickness ofthe leaves desired, and sawtowards the centre to within three inches of theisame, consideringr thelength, thereby mal-:ing the upper `leaves B B and the under leaves CC,.and so that all the said leavesishall be `of suitable thickness. AnilI thea insert fulcrurn-bloclcs d d between the said leaves, on each sideof the centre, :tt-suit able distances therefrom, towards each en d ofthe spring, thereby slightly separating the said leaves `and giving theleaves A A and A A a slightly curved appearance. I have the attachmentson the bedstead at eaoh'end thereof, on which the spring-rests extendunder the ends et' the lower leaves C Cl a short distance so as toreceive the bearing of the ends'of the lower leaves C C when the springis compressed at or near4 the centre, between the fulcrumblocl s d ci.

Having Athus described the construction of my compound bed-spring, Iwill now proceed to describe its operation andthe advantages gained byits use. i

When in position for use said spring rests at each end on suitableattachments fastened to the bedstead at the head and foot thereof. vWhenweight or pressure is applied at or near the centre of the spring, theopposite surfaces, between the fulcrum-blocks (Z d', approach eachother, and the ends of the leaves B B and C C are separated from ahorizontal line, th'e pressure `over the said fulcrurn-bloclis having atendency to depress the lowerleav-es C C', and thus lower said fulcra,while their ends remain stationary, and before said inside surfaces comein Contact with each other the ends of the lower 'leaves C C vstrike.the attachments, upon the'bedstead, as abovenientioned, and therebyproduce the effect of a second or double spring, in addi! tion to thatobtained withoutthe striking of the ends of said leaves C C upon suchattachments, so extended as aforesaid. When the pressure is applied tothe spring in position, as aforesaid, the ends of the upper leaves B Bwill be elevated, which will give great ease and comfort to the, personlying thereon by naturally elevoting both ends of the bed and adaptingit to the body.

i The advantages of this spring are its cheapness, itseasiness ofmanufacture, its durability, the noiselessvness of its operation, andits perfect adaptability to the most easy, comfortable, and natura-lposition of the body ofthe occupant. And if for any reason it is desiredto change ends with it or turn it over, it will work just as well asbefore.` This spring possesses all the desirable qualities of the mostcomplicated and expensive devicesnow being manufactured for the pur-posefor which it is designed.

In the drawings, Figure'l is a side view.'

In the drawings, Figure 2 is a pla-nevicw.

What I claim as my invention or improvement, and wish to secure byLetters Patent, is-

A compound bed-'spring consisting ofthe middle leaves A A', the upperleaves BB, and lower leaves C C', the several springs beingr supportedby the fulcruin-blocks rl d, constructed and arranged as and for thepur- .pose specified.
